Pick n pack scooper

ABSTRACT

A pet waste disposal device has a handle, a body, and a waste handling portion with two opposing scoops, which pivot outwardly between an open position and a closed position. A heating block and a pressing block extend along the free edges of the opposing scoops. Current from a power source, operable at the handle, runs through a heating wire on the heating block to seal pet waste within a plastic bag pressed between the contact faces of the heating block and pressing block.

The Pick n Pack Scooper has two technologies working side by side.

1: Electronic

2: Mechanical

DESCRIPTION

The Pick n Pack scooper needs five AA batteries incased in a batterypack, shown on page 2—fig B, to generate heat to seal the plastic bag.More or less batteries can be used in bigger or smaller size scoopers.Batteries can also be rechargeable.

Hold the Pick n Pack scooper with grab handle, shown on page 1—fig A andpull the pull handle with fingers to open the scooper claws. The pullhandle is attached to the inverted U shaped puller by a threaded steelrod. When pulled the U attachment opens the scooper claws and the clawsclose when the handle is released. Two steel springs provide the tensionto close the scooper claws. Lock the claws in open position by pressingthe handle lock, handle lock is shown on page 2—fig B. Install anappropriate size plastic bag inside the open claws of the scooper andrelease the lock. The scooper is now in close position with the open endof the bag hanging out of the scooper. Now fold the extra bag over theouter side of the scooper and stick it to the sticky strip on the outersurface of the scooper. A double sided sticky strip is installed on theouter side of the scooper to keep the plastic bag from moving when thescooper claws are open to pick up the waste. The Pick n Pack scooper isnow ready to pick up the waste.

Open the claws to pick up the waste and after the pick up press themomentary push switch, shown on page 1—fig A, for few seconds. The DCpower from the battery pack heats up the heating element wire instantlyand seals the plastic bag by melting the part of the bag that is pressedbetween the bottom edges of the scooper claws. As shown on page 5—fig E(top view) and fig F (front/side view) the inside bottom edge of onescooper claw the heating heating element wire of the bag sealer isinstalled around a rectangle hard plastic block, that is the same sizeof the inside of the scooper claw. The wire has two small steel springsat both ends, shown on page 5—fig E and fig F, to keep it at the sametension during the heating and cooling of the wire as the wire expandsand shrinks during the sealing process. The other scooper claw has ahard rubber strip of the same size as the inside of the claw. It is alsothe same thickness as the heating element plastic strip installed insidethe other claw, also shown on page 6—fig G. When the plastic bag ispressed between the heating and the rubber strips and the wire is heatedby pressing the momentary push switch installed on the grab handle, thebag is sealed. Once the bag is sealed with the waste inside, open thescooper and the sealed bag drops out because of the weight of the waste.

1. The main difference between Pick n Pack scooper and an ordinarypooper scooper is the bag sealer installed at the inner bottom edges ofthe scooper claws so when a plastic bag is pressed between the bottomedges it can be sealed by using the battery operated bag sealer. I wantto patent the use of battery powered bag sealing capability in thescooper.
 2. The other difference is the extended side walls of thescooper claws that always overlap each other at open or close position.The overlapping side walls prevent the plastic bag from sticking outfrom the sides. Only the open side of the bag sticks out from the bottomedges of the scooper claws and can be sealed by using the bag sealer. Iwant to patent the use of overlapping side walls of the scooper. Nomeasurements are provided in this application because the Pick n Packscooper can be made in different sizes, bigger or smaller.
